New MIG Gun Liner System Reduces Downtime to Address Burnbacks and Wire-Feeding Issues
Tregaskiss Posted 04/02/2013
To minimize costly downtime and prevent quality problems associated with incorrect MIG gun liner length, Tregaskiss has introduced its new QUICK LOAD™ Liner AutoLength™ System. The new system can be used with guns equipped with QUICK LOAD™ Liners, specifically the Bernard™ T-Gun™ Semi-Automatic Gun and Tregaskiss™ Robotic MIG Guns. The new system helps reduce wire-feeding problems and also decreases burnbacks, along with premature contact tip failure and wear associated with misalignment between the liner and contact tip.
A spring-loaded module housed inside the power pin applies constant pressure on the liner, keeping it seated properly in the retaining head (or diffuser) at all times. The new system allows for up to 1 inch (2.54 cm) forgiveness and it also accommodates liner movement during welding.
Once the AutoLength Pin has been installed at the rear of the gun, a Tregaskiss QUICK LOAD Liner can then be installed from the front end of the MIG gun in less than half the time and effort of a conventional MIG gun liner replacement — and without the need to cut and waste wire. QUICK LOAD Liners also allow the MIG gun to remain attached to the wire feeder during changeover, eliminating the need to climb up to remove semi-automatic guns connected to a boom wire feeder. They also allow welding operators to change the liner from a safe zone in a robotic cell during routine pauses in operation.
To simplify an upgrade to the QUICK LOAD Liner AutoLength System, Tregaskiss has developed a System Upgrade Chart that provides part numbers for the system according to common wire diameters and wire feeders from popular manufacturers. Also as reference, Tregaskiss has made available a helpful brochure.
